Overview of 100 United Nations Plaza

100 United Nations Plaza, completed in 1986, is a 267-unit residential tower in Manhattan's Turtle Bay neighborhood, offering panoramic views of the East River and the New York City skyline. The building stands out for its thoughtful design, with all residences featuring private outdoor spaces, floor-to-ceiling windows, and separate bedroom wings with en-suite marble bathrooms.

The apartments have been modernized to include high-end appliances, granite countertops, custom cabinetry, and washer/dryers. Interior layouts feature large galleries, walk-in closets, wood flooring, and pantries, creating spacious and functional living spaces.

Residents enjoy comprehensive amenities including a full-time doorman, concierge, state-of-the-art security system, conference suite/party salon, and a fitness club with pool. The building's private garden plaza, designed by renowned landscape architect Thomas Balsley of Riverside Park waterfront fame, provides a serene outdoor retreat.

The location adjacent to the United Nations offers convenient access to several green spaces, including Dag Hammarskjöld Plaza and the East River Esplanade. The neighborhood provides easy access to local restaurants and boutiques, making it a well-situated residential address in Midtown East.

This "exceptionally well-run" 51-story tower offers "dramatic" UN views from its prime Turtle Bay perch. The "sophisticated" building impresses with a "striking" brick-and-glass facade, "grand" drive-in porte-cochere and "spectacular" multi-level garden plaza complete with waterfall. While interiors may be "dated," "world-class" amenities abound including a 5000 SF fitness center, pool and 24/7 staff. The "prestigious" location near Grand Central, Tudor City and Beekman Place puts Manhattan at your doorstep.
